Carbon capture and storage – a vital part of our climate change response

One of the biggest challenges in our fight against climate change is reducing greenhouse gas (GHG) emissions from the energy sector. Approximately 87% of current global primary energy supplies (and 67…

Carbon leaking from land into streams

Rivers and streams in the United States are releasing substantially more carbon dioxide into the atmosphere than previously…
